Description

Breathe self-adaptation's portable oxygenerator

Technical Field

The invention relates to the technical field of medical appliances, in particular to a portable oxygen generator with self-adaptive breathing.

Background

The oxygen generator is available in the market and has different application characteristics due to different oxygen generating principles. The oxygen making principle of the oxygen making machine is as follows: molecular sieve principle, high molecular oxygen-enriched membrane principle, electrolytic water principle and chemical reaction oxygen-generating principle. For example, molecular sieve oxygenerator principle of operation: molecular sieve physical adsorption and desorption technology is utilized. The oxygenerator is filled with molecular sieve, nitrogen in air can be adsorbed when the oxygenerator is pressurized, and the residual unabsorbed oxygen is collected and purified to obtain high-purity oxygen. The molecular sieve discharges the absorbed nitrogen back to the ambient air when the pressure is reduced, and can absorb the nitrogen and prepare oxygen when the pressure is reduced next time, and the whole process is a periodic dynamic circulation process, and the molecular sieve is not consumed.

Along with the continuous improvement and improvement of the living standard of people, the demand for health is gradually increased, and oxygen inhalation is gradually an important means in home and community rehabilitation. However, the existing oxygenerator also has the harm of excessive oxygen absorption, namely, so-called 'oxygen poisoning'. Excessive oxygen inhalation can cause the destruction of the pulmonary capillary barrier, resulting in pulmonary edema, pulmonary congestion and hemorrhage, severely affecting respiratory function, and further causing damage to various viscera due to hypoxia.

However, the above-mentioned problems are mostly caused by excessive oxygen inhalation due to the inability to perform self-adaptive respiration according to the personal characteristics of the patient; and though the existing oxygen generating device is mostly provided with casters, so that the movement is convenient, the device is easy to collide or generate larger vibration due to other factors in the movement, and the service life of the whole device is seriously influenced. In view of the above, the invention designs a portable oxygen generator with self-adaptive breathing.
